User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:61.0) Gecko/20100101 Firefox/61.0 Build ID: 20180815084633 Steps to reproduce: Go to example of `mask-image` on MDN: https://developer.mozilla.org/en-US/docs/Web/CSS/mask-image#Example Add SVG fragment `#layer1` to the `mask-image` property of `#masked` See https://codepen.io/kidwm/pen/OoMoGO Actual results: The background disappeared Expected results: Show a green star just like Google Chrome

Regression window: https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=5f721a664bf64fed99184a866b60c24a6afcb3a0&tochange=62cebea1d1578461a423a9ca7848706455db9ea5 Regressed by: Bug 1330412

This looks very related to the work that happened in bug 1301245.

Cam, do you know what's supposed to happen here? Chrome seems to always disregard the fragment, that is, in that example, it doesn't matter whether it's `foo.svg#layer1` or `foo.svg#somethingthatdoesntexist`.

Hi, Emilio, Chrome does regard the fragment, see my updated version of https://codepen.io/kidwm/pen/OoMoGO

This reminds me that, fragment there is actually an ambiguous case, because it can either mean it is as <mask> with id specified, or an image with the specific target element specified. Related discussion in CSS working group can be found in w3c/csswg-drafts#383. The resolution was that, when there is a fragment, browsers should try loading it as a <mask> first, and if there is no such valid <mask> element with given id, reload the file as an image. Maybe we don't load it as an image?

But it is weird that, this does sound like something should happen in later place of the pipeline, but this is indeed a stylo regression (running a Firefox 57 and switching the stylo pref can see the different behavior). So the question would be what data does it trigger downstream difference...

This is a more extensive testcase which checks the three possible ways of using SVG: 1. using the SVG itself as image 2. using the SVG with fragment as image 3. using a <mask> element in the SVG file It seems that Chome doesn't support 3, while post-stylo Firefox doesn't support 2. Pre-stylo Firefox supports all three types, so there is still some unknown difference from the style system.

I think I know where the problem is now...

It seems like it could be related to mMightHaveRef in the URL structure.

I think I found the right fix, and my local build works with my test case now.

The corresponding handling code in the old style system can be found in: https://dxr.mozilla.org/mozilla-esr60/rev/dd52b41d2b775e5c7261ce52795268b7670635fc/layout/style/nsCSSDataBlock.cpp#65-106 mask-iage-url-hash.html is the test that don't pass without this change.

Looks like this bug has also made WPT tests mass fail.

That is because the patch was from a relative old base, and phabricator cannot handle large files like MANIFEST.json properly. I treat it as binary file this time, which makes it override the changes in-between, and that consequently caused this mess. See bug 1446555.

Backout by dluca@mozilla.com: https://hg.mozilla.org/integration/autoland/rev/0cd50dd88b53 Backed out changeset a0621cac7491 for wpt failures on /css/css-masking/mask-image/mask-image-url-remote-mask.html

High frequent intermittent failure on mask-image-url-remote-mask.html... Maybe we don't have onload blocker for remote SVG file loading?

The intermittent doesn't reproduce on my Windows machines, nor does it happen in my Ubuntu VM, even with all parallelism disabled...

(In reply to Xidorn Quan [:xidorn] UTC+10 from comment #25) > The intermittent doesn't reproduce on my Windows machines, nor does it > happen in my Ubuntu VM, even with all parallelism disabled... * "Windows machine"... I only tested it on one machine.

Upstream web-platform-tests status checks passed, PR will merge once commit reaches central.

Filed bug 1488300 for testing side work to avoid adding such hack. But I guess this doesn't need to be blocked by that.

Is there a high enough user impact of this bug that we should consider it for ESR60?

It was regressed by stylo in Firefox 57, and as far as I'm aware, this is the first report, so I don't think there is a high impact. Also users really annoyed by this bug are still able to switch off stylo in 60esr.
